Old Bethpage is a hamlet and census-designated place (CDP) located on Long Island in the Town of Oyster Bay, Nassau County, New York, United States.

Old Bethpage and its neighboring hamlet, Plainview, share a school system, library, fire department and water district.

Law enforcement for the community is provided by the Nassau County Police Department's Eighth Precinct.

In 1695, Thomas Powell bought about 10,000 acres (40 km2) from local Indian tribes, including the Marsapeque, Matinecoc, and Sacatogue, for 140 English pounds.

[3][4] For a few years, regularly scheduled passenger traffic also appeared in timetables, with the station named Bethpage.

Remnants of a locomotive turntable can be found in the woods of Bethpage State Park on the east side of Round Swamp Road.

[8] In 1908, William Kissam Vanderbilt II began construction of the Long Island Motor Parkway, one of the country's first highways.

Eventually stretching 45 miles (72 km) from Queens to Lake Ronkonkoma, New York, a portion of the parkway ran through Old Bethpage.

Street names such as "Vanderbilt Lane", "Motor Parkway" and "Toll Place" serve as reminders.

Located on Winding Road, the academy provides training to all Nassau County fire departments.

[20] According to the United States Census Bureau, Old Bethpage has a total area of 4.1 square miles (11 km2), all land.

[23] Opened in 1963 on a former Powell family farm, the restoration is an authentic recreation of a mid-19th century Long Island village.

The complex includes farmhouses, a blacksmith, general store, cobbler, school house and churches, all of which were moved to the site from other locations on Long Island and then restored to period condition.

However, in the 1970s it began to show pornographic movies until community protests forced the theater to revert to its original general commercial offerings.

[32] Old Bethpage is home to "Skate Safe of America", which provides facilities for roller hockey and other indoor sports.

For out-of-towners, the town is also home to the Battle Row Campground, which provides accommodations for trailers and tent camping on its 44 acres (180,000 m2).
